Description
本發明為有關一種投影裝置，尤指一種具有霧化導電結構的投影裝置及其應用。The invention relates to a projection device, in particular to a projection device with an atomized conductive structure and an application thereof.
隨著顯示技術的發展，顯示屏幕的應用面越來越廣泛，且為了滿足不同的需求，而有各式各樣的發展，其中，大尺寸的顯示屏幕為主要的發展之一，如應用於投影屏幕以及戶外廣告電子看板等地方。常見的戶外廣告電子看板有液晶顯示屏幕以及LED陣列彩色屏幕，液晶顯示屏幕的製程成本會隨著尺寸的增加而大幅增加，而LED雖然耗電量小，但製作成大尺寸的LED陣列彩色屏幕需要耗費大量的LED，其耗電量與製程成本也不容小覷，且像素顆粒感太強，使動態畫面的顯示能力也相對稍差。因此，如何降低戶外廣告電子看板的製程成本與耗電量，實為一急需解決的問題。With the development of display technology, the application of display screens is more and more extensive, and there are various developments in order to meet different needs. Among them, large-size display screens are one of the main developments, such as application. Projection screens and outdoor advertising electronic billboards and other places. Common outdoor advertising electronic billboards have liquid crystal display screens and LED array color screens. The process cost of liquid crystal display screens will increase greatly with the increase of size. However, although the LED consumes less power, it is made into a large-sized LED array color screen. It takes a lot of LEDs, and its power consumption and process cost are not small, and the pixel graininess is too strong, which makes the display capability of dynamic pictures relatively poor. Therefore, how to reduce the process cost and power consumption of outdoor advertising electronic signage is an urgent problem to be solved.
此外，隨著投影器材的解析度上升，在人眼可容忍的範圍內，可投影的面積越來越大，但須額外配置大面積投影屏幕搭配使用，相對小面積的投影屏幕，其所佔據的空間也較大，而為了減少投影屏幕所佔據的空間，美國專利第US 20140078410號之「Switchable Projection Window」，其揭露一種可調變的投影窗戶，其包含有一第一基板以及一第二基板，該第一基板包含複數個液晶微粒，該些液晶微粒隨著外加電壓的控制而呈現透明與不透明的狀態，該第二基板耦合至該第一基板，並具有一可變調光結構，而可控制光線的穿透與否。當一投影機朝該第一基板投影時，該第一基板切換為不透明狀態，而呈現一投影影像，而當該投影器不投影時，該第一基板切換為透明狀態，並配合該第二基板的調控，而可使外部光線穿透進入室內。In addition, as the resolution of the projection equipment rises, the area that can be projected is larger and larger within the range that the human eye can tolerate, but an extra large projection screen is required for use, and a relatively small area of the projection screen occupies In order to reduce the space occupied by the projection screen, the "Switchable Projection Window" of US Pat. No. 20140078410 discloses a variable projection window including a first substrate and a second substrate. The first substrate comprises a plurality of liquid crystal particles, the liquid crystal particles exhibit a transparent and opaque state under the control of an applied voltage, the second substrate is coupled to the first substrate, and has a variable dimming structure, and Control the penetration of light. When a projector projects toward the first substrate, the first substrate switches to an opaque state to present a projected image, and when the projector does not project, the first substrate switches to a transparent state, and cooperates with the second The regulation of the substrate allows external light to penetrate into the room.
將投影屏幕與窗戶結合在一起，雖然可以透過控制液晶的排列方向而節省設置投影屏幕的空間，但是，液晶不耐紫外線的照射，其長時間的接受太陽光與投影機所投射之光線，無法避免紫外線的照射，會使液晶的使用壽命減少，而需要進行替換，增加使用上的成本。因此，如何在節省設置投影屏幕的空間的同時，也減少使用成本亦為相關業者所需努力的目標。Combining the projection screen with the window, although the space for setting the projection screen can be saved by controlling the arrangement direction of the liquid crystal, the liquid crystal is not resistant to ultraviolet rays, and the light that is projected by the projector and the projector cannot be received for a long time. Avoiding the irradiation of ultraviolet rays will reduce the service life of the liquid crystal, and need to be replaced to increase the cost of use. Therefore, how to save the space for setting the projection screen and reduce the use cost is also a goal of the related industry.
本發明的主要目的，在於解決可投影之窗戶採用液晶結構，因而具有不耐紫外線之缺點，而使使用壽命減少，增加使用成本的問題。The main object of the present invention is to solve the problem that the projection window adopts a liquid crystal structure, and thus has the disadvantage of being incapable of being resistant to ultraviolet rays, thereby reducing the service life and increasing the use cost.

續搭配參閱「圖2」所示，上述第一實施例可應用於太陽能系統中，如本發明之第二實施例，其係提供一種利用霧化導電結構的光伏帷幕投影裝置，包含有一太陽能顯示模組10以及一投影模組20，該太陽能顯示模組10依序包含有一第一透明基板12、一電極層16、一光電轉換膜15、一透明導電氧化層14以及一第二透明基板13，該透明導電氧化層14包含有一霧化表面141，該光電轉換膜15包含有一相鄰於該電極層16遠離該第一透明基板12的N型半導體層153以及一相鄰於該N型半導體層153遠離該第一透明基板12的P型半導體層152。於此實施例中，該電極層16與該透明導電氧化層14的材質皆為透明導電材質，可為氧化鋅、氟化錫氧化物、鋁鋅氧化物、鋅鎵氧化物或其組合等，且該N型半導體層153與該P型半導體層152亦具有一定的透光度。需特別說明的是，本實施例所舉例的僅為PN介面的太陽能電池，而例如硒化銅銦鎵太陽能電池(Copper Indium Gallium Diselenide, CIGS)、碲化鎘（CdTe）以及染料敏化太陽能電池(Dye Sensitized Solar Cell, DSSC)等薄膜太陽能電池皆可作為本案之太陽能模組使用。Referring to FIG. 2, the first embodiment described above can be applied to a solar energy system. According to a second embodiment of the present invention, a photovoltaic curtain projection apparatus using an atomized conductive structure includes a solar display. The module 10 and a projection module 20, the solar display module 10 includes a first transparent substrate 12, an electrode layer 16, a photoelectric conversion film 15, a transparent conductive oxide layer 14, and a second transparent substrate 13 in sequence. The transparent conductive oxide layer 14 includes an atomization surface 141. The photoelectric conversion film 15 includes an N-type semiconductor layer 153 adjacent to the first transparent substrate 12 adjacent to the electrode layer 16, and an adjacent to the N-type semiconductor. The layer 153 is away from the P-type semiconductor layer 152 of the first transparent substrate 12. In this embodiment, the material of the electrode layer 16 and the transparent conductive oxide layer 14 are transparent conductive materials, and may be zinc oxide, tin oxide oxide, aluminum zinc oxide, zinc gallium oxide or a combination thereof. The N-type semiconductor layer 153 and the P-type semiconductor layer 152 also have a certain transmittance. It should be particularly noted that the solar cell of the PN interface is only exemplified in this embodiment, and for example, Copper Indium Gallium Diselenide (CIGS), cadmium telluride (CdTe), and dye-sensitized solar cells. Thin film solar cells such as Dye Sensitized Solar Cell (DSC) can be used as the solar module of this case.
該投影模組20，包含有一相鄰於該第一透明基板12的投影鏡頭21，該投影鏡頭21朝該第一透明基板12投射一投影光線，經該透明導電氧化層14之該霧化表面141的散射作用，而分別於該第一透明基板12之一投影面121以及該第二透明基板13之一背投影面131形成一投影影像22以及一背投影影像23，因此，此實施例亦可同時於該投影面121及該背投影面131上觀看到所投影的影像。The projection module 20 includes a projection lens 21 adjacent to the first transparent substrate 12, and the projection lens 21 projects a projection light toward the first transparent substrate 12, and the atomization surface passes through the transparent conductive oxide layer 14. A projection image 22 and a rear projection image 23 are formed on one of the projection surface 121 of the first transparent substrate 12 and the rear projection surface 131 of the second transparent substrate 13 respectively. Therefore, this embodiment also The projected image can be viewed simultaneously on the projection surface 121 and the rear projection surface 131.
續搭配參閱「圖3」至「圖5」所示，為本發明的第三實施例，與第二實施例不同的是，該電極層16的材質為金屬，如銀、鋁等材質，該電極層16、該P型半導體層152及該N型半導體層153具有複數個間格設置並位置對應的透光間隙161，因此，該電極層16可以反射該投影光線而於該投影面121形成該投影影像22，並穿透過該些透光間隙161的該投影光線則同樣被該霧化表面141散射，而於該背投影面131形成該背投影影像23。該些透光間隙161為利用雷射融蝕或化學蝕刻等方式對該電極層16、該P型半導體層152及該N型半導體層153進行融蝕或蝕刻。以雷射融蝕來說，先將該電極層16、該N型半導體層153、該P型半導體層152以及該透明導電氧化層14依序形成於該第一透明基板12上後，再將該第二基板13設置於該透明導電氧化層14上，將一光罩置放於該第二基板13上，再使用一雷射透過該光罩對該電極層16、該P型半導體層152及該N型半導體層153進行融蝕，使其分別具有位置對應的鏤空區(未圖示)，以形成該些透光間隙161，由於可搭配使用特定的雷射，因此透明的該透明導電氧化層14可以不被雷射融蝕掉，僅熔蝕該N型半導體層153、該P型半導體層152以及該電極層16，而任何可以形成該些透光間隙161的方式皆可以應用於此，不以此為限。此外，由於該N型半導體層153、該P型半導體層152可以具有一定的透光度，因此，可以僅對該電極層16進行融蝕或蝕刻而產生該些透光間隙161。Referring to FIG. 3 to FIG. 5, a third embodiment of the present invention is different from the second embodiment in that the electrode layer 16 is made of a metal such as silver or aluminum. The electrode layer 16 , the P-type semiconductor layer 152 and the N-type semiconductor layer 153 have a plurality of transparent gaps 161 disposed at a position corresponding to each other. Therefore, the electrode layer 16 can reflect the projection light and form on the projection surface 121 . The projection image 22 and the projection light that has penetrated through the light-transmissive gaps 161 are also scattered by the atomization surface 141, and the rear projection image 23 is formed on the rear projection surface 131. The light-transmitting gaps 161 ablate or etch the electrode layer 16, the P-type semiconductor layer 152, and the N-type semiconductor layer 153 by laser ablation or chemical etching. In the case of laser ablation, the electrode layer 16, the N-type semiconductor layer 153, the P-type semiconductor layer 152, and the transparent conductive oxide layer 14 are sequentially formed on the first transparent substrate 12, and then The second substrate 13 is disposed on the transparent conductive oxide layer 14 , and a photomask is placed on the second substrate 13 , and the electrode layer 16 and the P-type semiconductor layer 152 are transmitted through the photomask by using a laser. And the N-type semiconductor layer 153 is ablated to have a correspondingly corresponding hollow region (not shown) to form the light-transmissive gaps 161. The transparent conductive layer is transparent because a specific laser can be used in combination. The oxide layer 14 may not be ablated by the laser, and only the N-type semiconductor layer 153, the P-type semiconductor layer 152, and the electrode layer 16 may be etched, and any manner in which the light-transmitting gaps 161 may be formed may be applied. Therefore, it is not limited to this. In addition, since the N-type semiconductor layer 153 and the P-type semiconductor layer 152 may have a certain degree of light transmittance, the light-transmitting gaps 161 may be generated only by ablation or etching of the electrode layer 16.
而於此實施例中，該透明導電氧化層14並未具有該些透光間隙161，但於實際製作時，亦可於該透明導電氧化層14製作出與該電極層16、該P型半導體層152及該N型半導體層153位置對應的鏤空區，以形成該些透光間隙161，並如「圖4B」所示，該些透光間隙161可以為圓形，且相互平行排列，但不以此為限，該些透光間隙161也可以為方形或菱形，只要該些透光間隙161平均分布，並可以使該投影光線穿過，而使背投影影像23完整的顯示於該背投影面131上即可。In this embodiment, the transparent conductive oxide layer 14 does not have the light-transmissive gaps 161. However, in the actual fabrication, the transparent conductive oxide layer 14 can also be formed with the electrode layer 16 and the P-type semiconductor. The layer 152 and the hollow region corresponding to the position of the N-type semiconductor layer 153 are formed to form the light-transmitting gaps 161, and as shown in FIG. 4B, the light-transmitting gaps 161 may be circular and arranged in parallel with each other, but The light-transmissive gaps 161 may also be square or diamond-shaped, as long as the light-transmitting gaps 161 are evenly distributed, and the projected light may be passed through, so that the rear-projection image 23 is completely displayed on the back. The projection surface 131 can be used.
續搭配參閱「圖6」至「圖7」所示，將本發明應用於一建築物30之一窗格31上，該建築物30具有一內部空間32，且該內部空間32應於該窗格31，如為將本發明之第一實施例應用於此，該顯示模組11設置於該窗格31，使該第一透明基板12相鄰於該內部空間32，該投影模組20則設置於該內部空間32之一桌面，或可懸掛設置於天花板上，只要該投影鏡頭21可以朝該顯示模組11投射該投影光線即可，當該投影光線投射到該透明導電氧化層14後，會被該霧化表面141散射，而於該投影面121上形成該投影影像22，以展示於該內部空間32，並於該背投影面131形成該背投影影像23，以展示於該建築物30之外，如此一來，早上於該內部空間32開會時，可以將本發明做為投影屏幕使用，取代習知不耐紫外線的液晶，增加產品可靠度及壽命，並可長時間使用，且顯示於該背投影面131上的該穿透投影影像22會因為早上太陽光強烈，而無法顯示出來，除此之外，亦可阻擋部分陽光進入室內，達到降低室內溫度的效果；而於晚上時，則可投影經左右相反處理過的投影影像22，使該背投影面131顯示該背投影影像23，因此，本發明亦可以做為戶外廣告電子看板使用，並可依照使用者的需求而調整該霧化表面141的霧度，使戶外廣告電子看板具有不同的視覺效果，以取代習知需要使用大量的LED的陣列彩色屏幕，使耗電量與成本大幅減少。因此，本發明可做為投影屏幕或戶外廣告電子看板使用，可以同時減少額外設置投影屏幕與戶外廣告電子看板的成本與空間。Continuing with the reference to FIG. 6 to FIG. 7 , the present invention is applied to a pane 31 of a building 30 having an interior space 32 and the interior space 32 is adapted to the window. In the case of the first embodiment of the present invention, the display module 11 is disposed on the pane 31 such that the first transparent substrate 12 is adjacent to the internal space 32, and the projection module 20 is It is disposed on one of the desktops of the internal space 32, or can be suspended from the ceiling, as long as the projection lens 21 can project the projection light toward the display module 11, when the projection light is projected onto the transparent conductive oxide layer 14 The projection image 22 is formed on the projection surface 121 to be displayed on the internal space 32, and the rear projection image 23 is formed on the rear projection surface 131 to be displayed on the construction. In addition to the object 30, the present invention can be used as a projection screen in the morning when the internal space 32 is met, instead of the conventional ultraviolet-resistant liquid crystal, which increases product reliability and life, and can be used for a long time. And displayed on the rear projection surface 131 The through-projection image 22 will not be displayed because of the strong sunlight in the morning. In addition, some sunlight can be blocked from entering the room to reduce the indoor temperature. At night, the projection can be reversed. The image 22 is projected so that the rear projection surface 131 displays the rear projection image 23. Therefore, the present invention can also be used as an outdoor advertising electronic kanban, and the haze of the atomizing surface 141 can be adjusted according to the needs of the user. Outdoor advertising electronic billboards have different visual effects to replace the array of color screens that are known to require the use of a large number of LEDs, resulting in a significant reduction in power consumption and cost. Therefore, the present invention can be used as a projection screen or an outdoor advertising electronic kanban, and can simultaneously reduce the cost and space for additionally setting the projection screen and the outdoor advertising electronic kanban.
